Topological Graph Theory delves into the embedding of graphs on surfaces, revealing geometrical and topological properties. It intersects with algebra, geometry, and topology, and is crucial for solving complex problems like the Four Color Theorem. Advanced topics include graph minors and knot theory, with applications in urban planning, electrical engineering, and quantum computing. Visual examples like the Möbius strip illustrate its principles.
